I'm leaning towards 1 & 2 (in no particular order), they all look interesting and stimulating so I'm having trouble choosing one. Is there anything I should know about career-wise? job prospects?

better descriptions are given below

Options

Electronics (Option I) is for students interested in integrated circuits, including fabrication technology, solid state devices, digital and analog circuits analysis and design, VLSI design, and computer-aided design and manufacturing; and for students interested in microelectromechanical systems, electromagnetics, acoustics, optoelectronics, plasmas, cryoelectronics, and antennas and propagation.

Communication, Networks, and Systems (Option II) is for students interested in networks, control, robotics, digital and analog communications, computer networks, signal processing, systems design and optimization, and power systems planning and operation; and for students interested in biology or medicine as well as electrical engineering, including biological sensors and signals, signal and image processing, and analysis and modeling of biological systems.

Computer Science (Option IV) is for students interested in design and analysis of algorithms, complexity theory and other theoretical topics, artificial intelligence, and computer graphics.

General Option (Option V) is for students whose interests are broad or are not yet focused on a specific field. This flexible option enables students to explore several areas of electrical engineering and computer sciences.

The broadest option is plain ol' electronics. You'll learn skills which are applicable anywhere, in any industry. You won't, however, learn much about computers, which are also in every industry these days. If you do a computer systems option, you'll likely skip some of the specialized EE courses like fields and power, and take some programming classes instead. A computer engineer is also valuable to just about every industry.

Communications is the narrowest of the three options you presented -- you'll likely get a job with a communications equipment manufacturer. If you really like communications, go for it -- but it will limit job opportunities (slightly) compared to the other two options.

Of course, you can always take a few extra classes to round out your knowledge, regardless of the option you choose, and get the best of both (or all three) worlds.

Maybe I'll do option 1 and take some of the communications classes as electives. I've heard that you can make the most money in communications and thats why most of the undergrads end up doing option 2. Do you know if that's true?

I see in your profile that your an EE grad student in the Bay Area, do you go to Berkeley?

Nope, I attend SCU. It may be true that comm EE make the most money, but in my experience, your school training alone will only take you so far -- an EE with one concentration can pick up additional skills very quickly. For example, I actually hold a bachelor's of computer engineering, but I work for a high-speed analog company doing almost entirely EE work. Go figure!
